Application filed January 7, 1910. Serial No. 536,862.

To all whom it may concern:

Be it known that I, ARTHUR PERRY Nun son, a citizen of the United States, residing at Le Beau, in the county of Walworth and State of South Dakota, have invented certain new and useful Improvements in Globes for Protecting Mantles, of which the following is a specification.

My invention relates to improvements in globes, and the leading object of my invention is the provision of an improved globe for gas lamps.

A further object of my invention is the provision of a globe especially adapted for use on either gas or electric arc lights employed in out-door lighting.

Another object of my invention is the pro vision of a globe of this character which is provided with means for preventing the mantles in the globe from being readily injured by the action of the elements.

VVit-h these and other objects of a like character as hereinafter pointed out in view, my invention consists in a globe embodying novel features of construction and combination and arrangement of parts for service substantially as described and as illustrated in the accompanying drawings.

Figure 1 represents a side elevation of a gas lamp equipped with my improved globe. Fig. 2 represents a bottom plan view of my device as applied to a globe, its position when opened being indlcated in dotted lines. Fig. 3 represents a vertical sectional view of my device, a fragmentary portion of the globe being shown to illustrate the method of attaching the device, said section being taken on the line 33 of Fig. 2. Figs. 4 and 5 represent enlarged perspective views of the lower and upper securing plate respectively.

In the drawings, in which similar characters of reference are employed to denote corresponding parts in the several views, the numeral 1 designates the frame or crown portion of the lamp, said portion being secured to and depending from the supply pipe 2, said pipe extending into the lamp and bearing on its lower end the illuminating or mantle bearing portion 3, while the lower edge of the frame is provided with the customary screws or like securing members L for securing the globe 5 in position.

The lower portion of the globe has the centrally disposed circular opening 6 therein surrounded by the depending flange 7, said opening affording access to the interior of the globe when the same is secured in position to the frame and being particularly adapted for the insertion of a lighter for lighting the burners.

In the use of globes of this type, it often occurs that when a strong wind is blowing or there is any similar disturbance of the elements, disturbed air will rush into the opening 6 and frequently destroy the man tles. To prevent this and preserve the man tles, thus saving a considerable expense caused by the necessity of replacing the mantles and also avoiding the annoyance of not having a light or of having but a feeble and ineflicient one when it is stormy and the necessity for the light therefore the greater, I secure to the globe my improved device adapted to serve as a closure for the opening and prevent air currents strong enough to do any damage from entering therethrough.

My device comprises the large disk 8 provided with the central opening 9, and the smaller disk 10 having a similar opening 11. The disk 8 is adapted to fit inside the globe and above the opening 6 and have its opening 9 correspond with said aperture, while the disk 10 is placed below the aperture in the globe and rests against the flange 7. To secure the two disks in position I employthe screws or bolts 12 passing through the openings 13 in the disk 10 and the openings 14: in the disk 8, said openings 14 preferably being surrounded on the under side by the lugs 15, if desired said lugs being internally threaded to engage the bolts 12, otherwise said bolts being engaged by suitable nuts for securing them in position.

Pivot-ally mounted beneath the disk 10 is a circular disk or plate 16, said plate being of the same size as the disk 10 and having.

an eccentrically disposed opening therein through which passes the bolt 17, said bolt extending upward through the other disks and being suitably secured in position in the same manner as the bolts 12, as will be understood by reference to Fig. 3. The plate 16 is normally swung to fit over and co incide with the disk 10, said disk 10 being countersunk or recessed around the openings 13 to permit the bolts 12 to make a flush joint with the under surface thereof, and the plate in this position thus serves as a closure for the opening in the disk and thus also as a closure for the opening in the globe which it subtends.

To enable the disk or plate 16 to be readily swung aside to light the lamp, I provide on the under side thereof the lug or projection 18 which forms a handle which may be grasped either manually or by a suitable implement such as is usually carried by lamp lighters, the plate thus being readily swung on its eccentric pivot and permitting of access to the interior of the globe, as is shown in the dotted lines, Fig. 2. By reference to said figure it will also be observed that if desired the surface of the plate adj acent the lug 18 may be suitably knurled or roughened to provide the match scratching surface 19, it thus being possible to light the match at the aperture of the globe and insert the same into the globe before it is blown out by the action of the elements, as is liable to occur when it is necessary to scratch the match elsewhere and move the same up toward the globe.

From the foregoing description taken in connection with the drawings the construction and operation of my device will be fully understood and its advantages readily apparent, and it will be seen that I provide a device which will positively protect the mantles or burners therein from the action of the elements, which can be readily lighted, and which will insure a satisfactory light at all times.

I claim:

1. In combination with a globe having an opening in the lower portion thereof, exteriorly and interiorly disposed disks surrounding said opening and having corresponding apertures formed therein, means engaged in the apertures for securing said disks together and clamping them against the globe, and means pivotally secured to the exterior disk forming a closure for the opening in the globe.

2. The combination with a dome, of a globe secured thereto, said globe having an aperture formed in the bottom thereof, plates clamped to the globe and surrounding the opening for reinforcing the globe, and eccentrically pivoted means secured to the plates and forming a closure for the opening, said means having an integral lug forming a handle portion to swing the means over and away from the opening.

In testimony whereof I afiix my signature, in presence of two witnesses.

ARTHUR PERRY NELSON.
